Abstract

An injection device, comprising an injection member (2) pressurizing and injecting a molten resin. A motion converting mechanism converts a rotating motion generated in an injection drive part (50) into the linear motion of the injection member (2). A load transmission mechanism transmits a load acting on the injection member in the form of the reaction of the molten metal to a deformation member (74) through at least a part of the motion converting mechanism. The load transmission mechanism comprises a thrust bearing (71) receiving the load, and the inner peripheral side of the deformation member (74) is installed on a bearing support member (73) supporting the outer periphery of the thrust bearing (71).
